TM1 REST API

Overview

The TM1 REST API is a new way of accessing data and everything else in TM1. Rather than being a proprietary API like old TM1 interfaces it is based on web standards making it accessible to a wide range of developers.

REST stands for REpresentational State Transfer and is an architectural style (not a standard) that has become the common way of designing API for applications on the internet. The TM1 REST API does however support the OData standard (v4) which provides a common way for accessing data through queries and also updating data. OData is used by multiple vendors and is supported by companies like Microsoft, SAP and of course IBM.
